Laser-MIG Hybrid Welding of Aluminum Alloy

Effect of Direct Irradiation of Laser Beam on Wire Melting

Abstract

Laser-MIG hybrid welding of aluminum alloy has been conducted by setting laser beam and wire separately, conventionally, to avoid interference of laser beam and arc. In this report, the authors reported a method by which laser beam was directly irrated across the wire in order to reduce arc current at a same wire feeding rate.
